以三苯基膦和特戊酸为配体，在室温下，Pd催化2-芳基苄基氯分子内C（sp2）-H活化合成了芴类化合物。所需的反应在室温下有效地进行，并且各种底物以优异的产率转化为相应的芴衍生物。
The synthesis of fluorenes by intramolecular Pd-catalyzed C(sp2)–H activation of 2-arylbenzyl chlorides was conducted at room temperature by using commercially available triphenylphosphine and pivalic acid as ligands. The desired reactions proceeded efficiently at room temperature, and various substrates were converted into the corresponding fluorene derivatives in excellent yields.
